BEFORE YOU BUY

Know before
you order.

Already have a Bluetooth OBD-II adapter? You may be good to go.

Check your setup
Will it work with my car?

Your car needs a compatible OBD-II diagnostic system. The OBDLink CX supports CAN, ISO 9141 and ISO 14230, but not J1850, which some older vehicles use. The Veepeak supports all five standard OBD-II protocols, including J1850.

Vehicle coverage and available readings vary. Check compatibility before ordering.

Can I leave it plugged in?

The OBDLink CX is designed to stay plugged into your car. Its BatterySaver mode draws less than 1 mA while idle to minimize battery drain. For the Veepeak, the manufacturer recommends unplugging it if your car will sit for more than a week. Follow the adapter’s instructions and consider your car battery’s condition.

Does the adapter include a Diagnostic Report?

The adapter supplies your car’s data. MechaOBD is free to download. Diagnostic Reports are optional in-app purchases, sold separately from the hardware.
